Method 1: Simple Sharpen Option

This first option is the easiest option to sharpen images in Photoshop, but it does not give you any control and it almost always falls short. We thus don’t recommend this first method. If you want to use the simple sharpen option, click ‘Filter’, click ‘Sharpen’ and then click ‘Sharpen’.simple sharpen

Method 2: Use High Pass Filter

The High Pass Filter is a great tool to sharpen images, but you must be careful. It might not always look good when printing. If you don’t have to print, it might be a very interesting sharpening option though. To sharpen images with the High Pass Filter, duplicate your layer by right-clicking the layer and selecting ‘Duplicate Layer’.Duplicate LayerClick ‘Filter’, click ‘Other’ and then click ‘High pass’.High PassThe High Pass Filter scans your image for sharp changes and other information, which normally indicates an edge or a line. It retains those pixels while supressing the rest of the image. Adjust the treshold to find a nice result that contains the edges of your image without an excessive amount of noise. Apply the High Pass Filter by clicking ‘OK’.High Pass FilterYou can now merge the new lines with the original image, by clicking ‘Normal’ and by using either the overlay, soft light or hard light option. This will eliminate some of the blur.OverlayMake the last adjustments using the ‘Opacity’ slider until you have an image that is sharper but not unrealistic, as in the following result.Sharper

Continue and click ‘Add Layer Mask’.Add Layer MaskYou want to make sure that you have black as your foreground and white as your background. What ‘Layer Mask’ does is, when you paint over in black, it hides all the bad stuff and brings the underneath through.

Method 4: Use Selective Sharpening

This final method is really handy and especially interesting if you want to isolate one part of an image and make that part more in focus.

Everything else is left as it was originally.Brush SharpenWe hope you now learned a lot about sharpening images in Photoshop!
